Patent number: 11166161Abstract: A method and a device for controlling user access to a wireless network are provided. According to an example of the method, during master/backup changeover between an master main board and a backup main board in a switch, an AP may start a timer in case of short-term communication interruption between the AP and an master AC due to the master/backup changeover. In this way, if the interruption is within an allowable time period, the AP may maintain connections between the AP and authenticated users instead of imposing offline on the authenticated users.Type: GrantFiled: May 30, 2018Date of Patent: November 2, 2021Assignee: New H3C Technologies Co., Ltd.Inventors: Jianyuan Peng, Guoliang Zheng

Patent number: 9853897Abstract: When a User Edge Device (UED) receives a unicast packet from a user side, the UED searches in a Media Access Control (MAC) table. When a matching entry in the MAC table is found, the UED forwards the unicast packet locally. When no matching entry in the MAC table is found, the UED transmits the unicast packet to a Network Edge Device (NED). When the UED receives a broadcast packet from the user side, the UED broadcasts the broadcast packet within a same Virtual Local Area Network (VLAN) of a local site and forwards to the NED.Type: GrantFiled: August 29, 2013Date of Patent: December 26, 2017Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Xiaoheng Song, Guoliang Zheng

Patent number: 9450856Abstract: According to an example, in a method and an apparatus for expanding member ports of a link aggregation group between clusters, each apparatus in a cluster receives a port joining link aggregation group message sent by a master control board on a master apparatus in the cluster. In response to an apparatus determining that a newly joined port is a port on the apparatus itself and also is the first member port in the link aggregation group of the cluster, the newly joined port is associated with the link aggregation group. By applying the method and the apparatus for expanding member ports of a link aggregation group between clusters in this manner, according to an example, the number of member links in the link aggregation group between clusters is able to be increased, and the robustness of the network interconnection between clusters is also able to be enhanced.Type: GrantFiled: December 20, 2012Date of Patent: September 20, 2016Assignee: HANGZHOU H3C TECHNOLOGIES CO., LTD.Inventors: Guoliang Zheng, Liang Chen

Publication number: 20150172194Abstract: The present disclosure describes traffic forwarding in a network where Virtual Local Area Networks (VLANs) are deployed over geographically dispersed sites. The network comprises a first edge device (ED) at a first site and a second ED at a second site. In one example, the first ED receives traffic from a host device within the first site. The received traffic is to be forwarded to the second ED via a virtual link established between the first ED and second ED. The first ED determines whether a bandwidth required by the received traffic exceeds a bandwidth threshold negotiated between the first ED and second ED for the first ED to forward traffic to the second ED via the virtual link. If the negotiated bandwidth threshold is not exceeded, the received traffic is forwarded to the second ED via the virtual link. Otherwise, traffic with high priority is selected from the received traffic and forwarded to the second ED via the virtual link.Type: ApplicationFiled: August 9, 2013Publication date: June 18, 2015Applicant: Hangzhou H3C Technologies Co., Ltd.Inventors: Xiaoheng Song, Guoliang Zheng

Publication number: 20150029855Abstract: The present disclosure relates to a traffic routing method and a traffic routing device. A member device of a stacking system receives traffic destined for a destination node. If there is at least one valid Equal-cost multi-path (ECMP) associated with an address of the destination node in a forwarding table, the member device routes the received traffic to the destination node through the at least one valid ECMP path. Otherwise, the member device selects at least one other member device of the stacking system for routing the received traffic, updates an ECMP path associated with the address of the destination node in the forwarding table to a stacking link connecting the member device with the selected at least one member device, and transmits the received traffic to the selected at least one member device.Type: ApplicationFiled: December 21, 2012Publication date: January 29, 2015Applicant: Hangzhou H3C Technologies Co., LTD.Inventors: Guoliang Zheng, Tiezhu Gong, Haifeng Zhao
